| Abstract: | The optimum mix proportions of high-volume fly ash cement are determined by analyzing the (influence) of different factors on the strength of the cement using the approaches of orthogonal experiment and graphing. The result shows that the high-volume fly ash cement,in which 50% of the 42.5 P.O cement is (replaced) by fly ash, and 1% chemical additive and 5% mineral admixture are added respectively, can meet the criterion of grade 32.5 as judged by GB1344-1999. Furthermore, several application examples of the cement developed by us in civil engineering are presented. |
